Abstract

La présente invention concerne un échangeur de chaleur disposé d'un côté dans une certaine direction par rapport à un corps de paroi dans lequel une ouverture de ventilation (92a), à travers laquelle un courant d'air passe, est formée, ledit côté dans ladite direction étant le côté aval du courant d'air. L'échangeur de chaleur comprend : un ensemble faisceau (14) ; un premier collecteur (21) ; un second collecteur (22). L'ensemble faisceau est conçu pour comprendre une pluralité de tubes (15) dans lesquels circule un agent caloporteur, chaque tube ayant une première extrémité (151) de tube et une seconde extrémité (152) de tube, et un échange de chaleur est effectué entre l'air ayant traversé l'ouverture de ventilation et l'agent caloporteur dans la pluralité de tubes. Les premières extrémités de tube sont reliées au premier collecteur, et une entrée d'écoulement (211), à travers laquelle coule l'agent caloporteur, est formée dans le premier collecteur. Les secondes extrémités de tube sont reliées au second collecteur pour faire circuler l'agent caloporteur. En outre, l'ensemble faisceau possède, dans une partie de tout l'ensemble faisceau, une plage de chevauchement d'ouverture (141) destinée à chevaucher l'ouverture de ventilation sur ledit côté dans ladite direction. L'entrée d'écoulement est disposée de sorte que l'agent caloporteur coule plus vers la région de chevauchement d'ouverture à l'intérieur de tout l'ensemble faisceau.
